Daewoo Relay Operation Without Heater Activation

Unit emits a clicking sound repeatedly but does not start heating.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Failed heater despite relay clicking, Relay contacts burned open, Broken heater wiring, Control board driving wrong output

Safety first: Unplug the air fryer and cool before inspecting internal components.

Steps:

1. Confirm sound source: The clicking is likely the heater relay on the PCB. Remove the cover to verify.
2. Test heater continuity: Measure resistance across the heating element. Replace if open.
3. Inspect relay contacts (advanced): If the heater is good, the relay may have burned contacts. Replace the relay or entire PCB.
4. Check wiring: Ensure the heater is actually connected to the relay output and that no wires are loose.
